DRIVING? No. genome,

To all whom it may concern: I

Be it known that I, Bnuuo REICHELT, o citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in. Driving Belts and Hopes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such auwill enable others skilled in the art to which it iipperteinu to moire and use the some.

My invention relates to driving belts or ropes, and its object is to improve that class of driving belts which are woven into, a, fabric rem hemp, cotton, flan or other material.

ln carrying out my inventiomleirri to provide a strong, water-prim, non-stretchable belt aniline-reuse its aclhceiveneso so that it in impossible or it to slip upon the pulley, and with these ends in View the improvemcnt consists in impregnating the interstices with a heated solution which is afterwards removed from the outer surlaces by eubjecting the belt to pressure between rolls; then impregnating the outer euriaccs with a second solution, then covering the outer side with a substance to give it a leatherlike appearance and render it \veter-prooi, and finally'lilling the intersticeeof the edges with a material which given it rigidity at those places to enable it to stand the strain brought to bear by shifting from. the driving pulley to the idler.

in the accompanying drawings which illustrate any improvement: Figure 1 is a perspective of o, port-ion of the belt. Fig. 2 is 2t perspective, oia portion of o driving rope treated in the some way-(1e the belt.

In the drawings, A designates the belt and B the rope. I The belt may be of any thickness and the ends of the interior warp threads and the Wei t or cross threads are shown at a while 1) undo indie-rite the outer or upper side and stiffened edges respectively.

In making the belt the am is first subjectd to the action of :1, solution of 599 parts of black stearin pitch, 80mm; of rosin free from ocidood 2tliparts oi 'caouv choucin which is a substitute for caoutchouc cozlnposed of a mixture of oil and rosin portly dissolved in other Specificetion of Letters Patent. Application filed Plural: 21, 19(32- llenewed-lebruary 28, M04; {Burial Etc. 195,4l8l).

solution is dry and hard the upper or outer surface is covered with a mixture of 2 ports cooutchoucin, 1 par!- nlcohol and 1 part of mixed yellow and red ocher. This renders the belt water-proof, and gives it a leather-like appearance.

By the constant shifting of the belt from the driving pulley to the idler, the edges frequently become etretched and sag, and to obviate this I till the interstices, ot the edges, with :1- solution of 1 part ceouh choucin, 1 part alcohol, 2 parts shellac and 1 part black soot.

Although this process is more particularly adapted for driving belie, I do not wish to confine myself to such use alone as numerous articles mode from felt or course iuhric may be uirnilzirly treatml, and in Fig. 2 l have shown a, driving rope composed of a plurality of strands I treated by this process.

Having thus described my invention, what I claim and desire to secure by Letters Patentisr r 1. The which conslste in immersing and impregnating the interslices wlth a hot solution, then subjecting the labric to preseure between rolls while the solution tnutlll hot and removing the uurpluu from the surfaces of the fabric, then passing the fabric cereals a space in which the u0lution may cool and burden, then treating the surfaces of the fabric with n 'sccond solution, panning the fabric qcross another space, and then treating the-outer surfaces with :1 third material to give a union to its surface.

2. The herein described method of ti'eatlng'fabrlc, which consists in immersing and impregnating the interstices with a heated solution, thenv subjecting the fabric to pressure between rolls while the solution is still hot and removing the surplue from the suffucen of the fabric, then cooling the fabric to permlt the solution to cooi'ond harden, then treating the surfaces of the fabric with a second solution, then drying and hardening the surfaces, and then treating the outer surface with 11 third solution to render it blather-liken :5. The herein described method of treating (li'lVlllg belts which consists in subjecting the belt to the action of a heated solution of black utearln pitch, ronln and moutchoucin, then removing the solution from the outer surfaces by presser rolls, then covering the outer surfaces with a solution to render thebelt waterproof and non stretchable.

4. The herein describellmethod of treating driving belts which consists in subjecting the belt to the actlon'of a heated solution 01" black steal-in pitch, rosin and snoutchoucln, then removing the solution from the outer surfaces by presser rolls, then impregnating the outer curtfacee with a solution of ciioutchoucln, alcohol our} black sootf'nrid then covering the outer side and edges with solutions to l-curler them water-proof, leather-like and non-stretchable.

herein described method of treating. 'lnliric,

5. The, herein described method of treating ririving' belts which consists in uuhjectlng the belt to the action of a heated solution oi black stenrin pitch, rosin and caoutchoucin, then removing the solution from the outer ity to clip on the pulley in obviated nicer the above surfaces by oresser rolls, then impregnating the outer surfaces with a solution of caoutchoucin, alcohol and black soot, and then covering the outer side with a solulion 0! caoutchoucin, alcohol, and a mixture of yellow and red. what, and finally imprgnuting the interstices at the edges, with a solution to prevent stretching.

G. The herelu described method of treating driving helfs which ('onflisfs in subjecting the halt to the action of a hented solution 01 black stearlu pitch, rosin and caoutchoucin, than removing the solution from the outer surfaces by pressei' rolls, then impregnating theouter surfaces with a solution at caoutchoucin, alcohol and hluvck soot. and then covering the outer side with a Solu- 5 mm of cumitchoucln, alcohol, and amixture of yellow and rail ncher, and finally impregnating the interstices nt iiw edges with a solution of caoutchoucim'nlcohol, shellac and black soot.

In testimony wlwz-eof I affixed my signature, in presence of two witnesses.
